Industrial & Manufacturing cleanup site — Restorical Research

Preliminary Site-Specific Analysis

This property has a documented history as a industrial and manufacturing facility predating 1986. Historical insurance policies issued during operations at this property and through 1986 could fund a cleanup.

This property operates as an active lumber mill and timber products facility in Winlock, with environmental concerns documented under Ecology's Standard Cleanup program since at least 2012. Areas of contamination concern include lumber-end paint-spraying zones, conveyor chain lubrication points, maintenance areas, and stormwater discharge points; rock staining at the site indicates past spills that were not properly remediated. A diesel-impacted area has been excavated and replaced with fresh gravel, but the site was listed as Awaiting Cleanup in 2015 and no comprehensive remediation has commenced. That history could support an insurance cost recovery claim against carriers who issued insurance policies 40+ years ago.

Why Historical Insurance Policies May Be Accessible

Pre-1986 Commercial General Liability (CGL) policies were occurrence-based and did not contain an effective pollution exclusion in Washington. If contamination occurred while those policies were active, those historical insurance carriers may still have a legal obligation to fund the cleanup costs, even if the business closed or the property changed hands.

Contamination at this site reflects the cumulative residue of routine industrial operations — diesel spills, lubricant releases, and paint overspray from ongoing milling activity — rather than any single, discrete incident. That pattern of incremental, operations-driven contamination is precisely what occurrence-based Commercial General Liability policies issued before 1986 were written to cover, before effective pollution exclusions became standard. Carriers who issued CGL policies to the lumber mill operator during its pre-1986 operating years may bear a share of the investigation and remediation costs the property now faces.

Restorical's role is to locate viable historical policies, determine whether a successful coverage claim is possible, and assist our clients and their legal counsel to obtain insurance coverage. Restorical then manages the claim, including accounting, to ensure the cleanup is funded in a timely manner.

The Restorical Proven Process

Task 1 — Research and Analysis
Restorical searches for viable historical insurance policies, researches the site history, analyzes the contamination impacts, and underwrites potential coverage — including a proprietary trigger analysis. At the end of Task 1, we provide a clear yes or no on whether a successful cost recovery is possible, along with a strategy and recommendation specific to your situation, even if you are not the policyholder.
Task 2 — Coverage and Funding
When Task 1 confirms viable coverage, Restorical works with your legal counsel to tender the claim, negotiate and secure insurance coverage. Restorical will manage the ongoing claim process, including accounting to ensure the insurance companies are funding your remediation in a timely manner.
